As of April 7 2023, the observatory will be OPEN each Friday evening -- WEATHER PERMITTING.

We will post alerts on the AAAP home page and Twitter sites when that information is available. Opening statuses may change depending on the weather conditions.

Please call the observatory at 609-737-2575 on Friday nights between 8:00 and 11:00 pm to find out if we are open.

*** (If no one answers, we are definitely closed.)

Openings are tweeted as soon as we know that the weather will cooperate, which is usually late Friday afternoon or early evening.

Check our Twitter page for the most current status information.
